      Description

      Hi,

      I upgraded mongo to 1.6.3 from 1.6.1 (using the apt repo) and after I restarted the config db, router and all the shards, I now get this in the mongo log:

      Fri Oct 1 15:41:21 [Balancer] lastPing is empty! this could be bad:

      { _id: "balancer", process: "domU-12-31-39-18-04-BA:1283870654:1804289383", state: 1, ts: ObjectId('4c8a8e9473876ed6c88ea3a6'), when: new Date(1284148884286), who: "domU-12-31-39-18-04-BA:1283870654:1804289383:Balancer:846930886", why: "doing balance round" }

      What does this mean and how do I fix it?

      Thanks,

      • Leo
